I bought this product one week ago, but it's not the first time I use this. I received one as a gift and it worked very good both on my acoustic and electric guitar's strings, but after almost 2 years I used all of it, so I neeed a new bottle.
I mostly use it on my electric guitar like once a week, and it works very well, it can double or triple the lifetime of a string, it keeps them very bright and clean, and the strings always sound like it was just put on, even after 4-5 months.
On my electric guitar I use coated strings and it works very well with that, and on my acoustic I use regular strings, and it works on it as well as on the coated strings.
pro:-god price
-it cleans the string very well and it protects it from corrosion
-it last long
cons:-none
I think this is the best string cleaner which you can find for this price and it can be used on any type of strings.
I recommend for everybody to try these,
